Festool Cleantec D36 (36mm) Hose Adapter to 2-1/4" ID Dust Ports, Friction Fit! This adapter is a friction fit between your D36 hose and 2-1/4" ID dust ports commonly found on jobsite table saws, Ridgid oscillating edge belt/spindle sanders (EB4424/R4840), and many others! This is the higher CFM flow hose connection that can be purchased separately from any Festool vendor and is greatly recommended for demanding applications (table saws, belt sanders, etc). The adapter features a taper on the dust port side to connect seamlessly with a tight fit. As the Festool hose-side is tapered, we left that side a consistent diameter that is meant to be snug when fully inserted. This adapter is 3D printed from PETG which is able to withstand greater abuse and heat in the shop than compared to PLA while being more flexible. As common with all 3D prints, the adapters features a seam line but this is low profile and does not affect the function or performance of the adapter.
